a request about SDHC support on WM6:
ASUS released a WM6 upgrade for P535 GPS-PHONE-PDA
it uses a core WM6, and an SDHC support with a SDHC_V5.CAB in the extended ROM. This cabinet file automatically installed from extended ROM, even after a hard-reset. So i suppose that, core WM6 ROM doesn't contain SDHC support (P535 uses mini-SD cards unlike Dell Axim x51v).
buggy ASUS files are: sdbus.dll, sdcard.dll, sdmemory.dll. if you delete them and Core wm6's dll files re-appears, than iGO works again !
iGO myway plus Navigator program doesn't work if you installed SDHC_V5.CAB
please check that if iGO is working or not if you try to add SDHC support with an un-official support like ASUS made
if you will use Microsoft made SDHC drivers, then iGO must release a compatible software.
